Protein Name: Tubulin beta-4B chain

UniprotKB/SwissProt ID: P68372 (P68372)

Gene Name: Tubb4b

Organism: Mus musculus (Mouse)

Function: Tubulin is the major constituent of microtubules, a cylinder consisting of laterally associated linear protofilaments composed of alpha- and beta-tubulin heterodimers. Microtubules grow by the addition of GTP-tubulin dimers to the microtubule end, where a stabilizing cap forms. Below the cap, tubulin dimers are in GDP-bound state, owing to GTPase activity of alpha-tubulin

Protein Subcellular Localization: Cytoplasm, cytoskeleton. Cytoplasm, cytoskeleton, flagellum axoneme
